Evergreen grass is a succulent alpine plant with high demand for light and good cold tolerance. The data show that some varieties can tolerate the lowest temperature of MINUS 30 degrees, and can be exposed to the sun all the year round in most parts of China. Although perennial grass is resistant to low temperature, it doesn't mean that it can be thrown into the cold outdoor immediately after being kept in a warm room for a long time. Plants can't stand any drastic changes in the environment. Evergreen grass can also accept conditional high temperature, that is, dry and ventilated high temperature. The highest temperature in my shed reached 48 degrees, and most of them were safe except for a few varieties with thin leaves.
First, the planting environment
The ideal environment for long grass is a rainy and windy mountainous area with poor soil, strong ultraviolet rays and cool weather. For us, there is no way to imitate this environment, and there is no need to imitate it. The adaptability and endurance of long grass to the environment exceeded my expectation. The best way for meat lovers to raise grass is in the open air. European growers even throw perennial grass directly on the roof and let it grow. If it can't provide an open air environment, the effect of the country will be discounted.
Second, flowerpots and soil preparation
Long grass hardly picks the medium, and any soil can be used. Players only need to choose the matching method according to their own maintenance habits. Need specific analysis of specific problems. Sometimes grass fans ask me how to mix soil. I can only say, "If the hand is cheap, the proportion of particles is large or even complete, and if the self-control is good, the proportion of peat is large." For ordinary vermicelli, one thing to grasp is the permeability of soil, and add some perlite appropriately. At present, my soil mixing method is: 2 portions of peat or sawdust, garden soil 1 portion, river sand 1 portion, vermiculite 1 portion, and appropriate amount of slow release fertilizer. I add river sand to enhance the water permeability of the soil, because I supply a large amount of water and work hard. Garden soil is more used as fertilizer. In terms of soil proportion, there are also differences between the north and the south. Dry in the north increases the proportion of peat, while wet in the south increases the proportion of particles. Generally speaking, to match according to personal preference and environment, no formula can be applied to all.
About pots, some people like porcelain pots, some people like pottery pots, and some people use small black squares. I think everything can be done without loopholes. The quality of plants is often under personal control, but some media and flowerpots are difficult to use.
Third, water and fertilize.
Long grass needs more water than most Sedum plants, especially in the growing season. In the dry north, it is best to keep the soil moist, as long as the leaves don't lodging and there is no need to cut off water. Whether the color of perennial grass is gorgeous is the result of the comprehensive action of climate, temperature and humidity. If there is more water, it will not be green.
Long grass has little demand for fertilizer, and ordinary slow-release fertilizers can cope with it. In the spring and autumn growing season, you can also simply spray a thin foliar fertilizer several times. Less or no fertilization will not cause any adverse consequences. If there is too much ammonia nitrogen, it will grow white or grow into a huge plant.

Fourth, light.
In the spring and autumn growing season, receiving enough sunshine is a necessary condition for long grass to reach its most beautiful state. In hot summer, perennial grass is in a semi-dormant state. At this time, you need proper shading, just cover it with ordinary shading net. If there is no sunshade net, it can be placed out of direct sunlight at noon.
Five, the long grass in summer
Many flower lovers turn pale at the smell of summer. It seems that summer is the most annoying. In fact, there are many benefits in summer, such as seedling raising and leaf cutting in early summer, which grow rapidly. In fact, it is not so difficult to spend the summer with perennial grass. Perennial grass, which is in a semi-dormant state at high temperature, will adjust the summer, that is, the color will turn green to avoid excessive heat absorption. Human intervention to strengthen the grasp of summer is to shade the sun, strengthen ventilation (it is best to have an electric fan for continuous sauna days), shelter from rain when it rains continuously, and avoid toxic days after rain, then we will prepare for the summer with long grass.
The first is to make the roots grow well to the maximum extent, and it is best to fill a pot. If it is a newly cut evergreen grass seedling, it needs more water to promote its growth.
Secondly, comb the places that are too dense and cut off the small heads that are stacked so as to have better ventilation. Some flower friends in coastal cities say that Xia Feng is very big there. I think we should get rid of some small heads, because macro-environment ventilation does not mean micro-environment ventilation.
Finally, control water. In the growing season, if the leaves of perennial grass fall down due to excessive water accumulation, the watering times should be gradually reduced and restored before midsummer as much as possible. Water cannot be completely cut off in midsummer, because the long grass is in a semi-dormant state, so it will not completely enter a dormant state. When the soil is dry, water it. The best way to water is to soak the pot, but don't soak it. Only supply some water to the capillary root at the bottom. The taproot above has no water absorption capacity and will rot if soaked for a long time. If there are many things, it is better to ventilate after soaking in the basin, such as blowing a fan.
Six, the reproduction of perennial grass
The main propagation mode of perennial grass is asexual seedling cutting. Sowing often can't get the complete character of the female parent, unless only one variety is planted in the collection area, it will bloom at the same time, which is very easy to cross. Some varieties have more babies in spring, and some varieties have more babies in spring and autumn. The most important breeding season is spring, so it is necessary to ensure adequate water supply.
The succulent plants of Eupatorium are very hardy. Even in Xinjiang, they can spend the winter in the open air and grow in spring, summer, autumn and winter, but they stop growing in summer and enter a dormant period. If you want your succulents to grow healthy and beautiful, you must pay attention to their growth period.
